Please add Mali 3D drivers to Lubuntu part and RGA 2D drivers for acceleration.
"as rockchip rk3066 and rk3188 devices are also equiped with ARM's mali 400 GPU for 3D acceleration, lgeek has made an improved version of ssvb's work https://github.com/lgeek/xf86-video-fbturbo and added support for rk3188 2D by using its hardware acceleration unit (RGA) and some specific optimization for copying video windows (XV)." Maybe it can work for RK3288 also.
Is it possible to update Lubuntu image to 16.04 instead of 14.04?

I have a question: How to build android 5.1 for the firefly rk3288 reloaded?

First I do:

cd ~/proj/firefly-rk3288-lollipop/kernel

make firefly-rk3288-reload_defconfig

make -j8 firefly-rk3288.img

Copy the code

And then:

cd ~/proj/firefly-rk3288-lollipop

. build.sh

make -j8

./mkimage.sh

Copy the code

But the built image does not reflect the HDMI outputs. I cannot change the output resolution. I cannot display 4K (max available is only 1080p).
For some reason it says "TARGET_PRODUCT=rk3288_box". I think it should be something like "reloaded" or something. Or maybe this has nothing to do with it.. maybe?
